Hi! Does anybody know that wether is it possible (and how) to plot a 3D->1D function, when I have this function only numerically, on random grid? (In this case the Interpolation[] does not seems to work) (random grid = not rectangular grid) Or in more simple case, a random grid is this: In[1]:= data={ {0,0,0},{0,1,1},{1,0,1}, {1,1,2},{0.25,0,0.25},{0.5,0,0.5} } In[2]:= f=Interpolation[data] Interpolation::indpt: Coordinate 0.5 in data point {0.5, 0, 0.5} does not match the corresponding coordinate in {0, 0.25, 1}. plese help. thanks Akos ps: Do you think I can Fourier transform this? does that help?
